- package progress
- /*
- The progress package contains functionality to deal with progress reporting.
- The functionality is built to serve progress reporting for infrastructure
- operations when talking the vSphere API, but is generic enough to be used
- elsewhere.
- At the core of this progress reporting API lies the Sinker interface. This
- interface is implemented by any object that can act as a sink for progress
- reports. Callers of the Sink() function receives a send-only channel for
- progress reports. They are responsible for closing the channel when done.
- This semantic makes it easy to keep track of multiple progress report channels;
- they are only created when Sink() is called and assumed closed when any
- function that receives a Sinker parameter returns.
